Valve Cover Bolt Kit 12pt GM Duramax 6.6L

The Valve Cover Bolt Kit 12pt GM Duramax 6.6L by ARP is a crucial upgrade for Duramax diesel engine owners aiming to prevent fatigue failures and valve cover leaks. This kit is particularly beneficial for those operating in high-stress environments, such as heavy towing or aggressive tuning.

Manufactured from aerospace-quality alloy steel, this 12-point bolt kit replaces the factory fasteners, which are susceptible to stress cracking and loosening. The superior tensile strength of ARP fasteners ensures consistent clamping force, preventing oil seepage and gasket separation. The 12-point head design enhances engagement, reducing the risk of stripping during installation.

This kit is specifically designed for LML and LGH Duramax models from 2011 to 2019, making it an ideal choice for owners who demand reliability and performance from their engines. With detailed torque specifications included, users can achieve the proper preload without risking damage to the aluminum valve cover or fasteners.
